Abstract (en)
[origin: WO2020030760A1] The invention provides a liquid laundry detergent composition comprising ethoxylated polyethyleneimine (EPEI) for an improved product viscosity profile without impairing cleaning performance; the detergent composition comprising: a) from 6 to 50% (by weight based on the total weight of the composition) of one or more detersive surfactants selected from non-soap anionic surfactants, nonionic surfactants and mixtures thereof, and b) from 2 to 15% of an ethoxylated polyethyleneimine (EPEI) having a polyethyleneimine backbone derived from a polyethylene starting material and made up of repeating -[(CH2CH2)N]- subunits; and one or more polyoxyethylene side chains which are bonded to internal and/or terminal nitrogen atoms in the polyethyleneimine backbone; in which the polyethyleneimine starting material has an average molecular weight (Mw) ranging from 1800 to 5000 g/mol (prior to ethoxylation), and the polyoxyethylene side chains have an average of from 25 to 40 ethoxy units per side chain bonded to the polyethyleneimine backbone.
